CALENDAR.

Application filed April 2,

structure of a writing instrument and, par- 'ticularly, within the cap of a fountam pen.

Another object of the invention resides in forming said calendar so as to include all of the months of a year. I

A still further objectrof the invention resides in employing a portion of a fountain pencap as a drum or holder for the recep tion of a table comprising a rolled sheet. having imprinted thereon the datesof the various months, and in providing a sleeve or sheath encircling the table and having a window therein, said sleeve being adapted to be rotated with respect to the table on the holder to expose thedifierent dates on the outer surface of said table.

A feature of the invention resides in printing the months of a year successively in columnar formation on a long sheet and in rolling said sheet into tubular form with the dates of one or more months exposed on the I outer surface of the roll and in gumming the edges of the rolled sheet to retain the same in cylindrical form.

A further feature resides in dividing saidtableinto sections by means of perforatlons extending across the same between the monthly demarkations thereon so as to permit of detaching the used sections and" exposing the unused sectionsin the course of the year.

With the foregoing and other objectsin view, which will appear in the following description, the invention resides in the novel combination and arrangement of parts and in the details of construction hereinafter described and claimed.

In the drawings:

N Fig. 1 isaperspective view of a fountain pen in which a form of my invention is embodied.-

Fig. 2 is an enlarged longitudinal sectional view of the .cap and a portiontof the barrel illustratedin Fig. 1.

Fig. 3 is a detail perspective'view on an enlarged scale of the table detached from its holder in the cap of the fountain pen and illustratingone ofthe sections of the table partly'extended from the roll.

In using a fountain pen for writing checks, as well as for numerous other purposes, it'frequently becomes desirable to as? 1927.- Serial noflsogiea,

certain a particular date in the current month. My invention meets such need by associating a tablewith thecap of the pen" in such a manner that appropriate portions of the same may be displayed to. indicate the dates of the month desiredif a For illustrating the application of the I invention, 1 have shownin Figs. 1 and 2 a fountain pen A comprising the usual barrel l0, pen point 11 andfeed member 12. The barrel is conventionally threaded at -13 to receive a cap lwhich, adapted to mypar ticular invention, preferably departs some what from the conventional form of cap. This cap is internally threaded at 15, as usual-,'to screw upon thethreaded portion 13 of barrel 10 and'is bored in the customary manner with a tapered bore 16 adapted to, fit snugly upon the tapered end. 17 of the barrel when the pen point llis exposed for Writing. The interior bore 17 of caplt is reduced near its outer end at 18 to form the customary. shoulder f 19 adapted to abut against the; end 20 of barrel 10, whereby the compartment containing the pen point, when in disuse, is rendered. air tight. The usualvent holes 21 may be drilled in 'the." czgp between the shoulder 19 and the threads As will be notedin Fig. 2, 'the end of the cap 14 is reduced in diamet er exteriorally'to resolve said end of the. cap into a drum-like holder 22 for the tubular table presently to. be describedand to provide a shoulder 23. The tip of the cap is formed withan axially disposed lug 24 which is externally threaded at 25 to receive'a nut or retainer 26 of substantially the same diameter as the lcap proper.- This lug 24 is of less diameter than the drum 22 providing a shoulder. 27, which in conjunction with the retainer 26serves' to clamp the ring portion 28 of a clasp 29 in place,

RUN

upon the end of the cap. This clasp is of ordinary construction. and is provided with a ball at the end of thesame for holding the pen in, the pocket of the wea ers clothing.

About the drum 22 is mounted arevolulole drum 22 adjacent shoulder 23. The other centric relation relative to said drum.

tapered Sleeve 32 is of such a length that the top thereof falls below the ring-like portion 28 of the clasp 29 and is held immovable longitudinally by means of the shoulder 23 and said ring-like portion, while the same may be freely rotated-upon the drum .22.

In conjunction with the drum 22 I employ a printed table indicated in its entirety at B. This table is formed from a long strip of paper having printed thereon, in

columnar formation, demarlrations 35 indicating the dates, days, and months of the year, the months being arranged successively along transversely across the strip. Between each monthly division the sheet is perforated along a transverse line 36 to divide the same into a number of sections 37. In preparing the table for application to the cap 14, the sheet is wound or rolled upon a suitable cylindrical mandrel starting with the last month of theyear with the printing thereon on the outer face of the sheet. While so rolled, the edges of the sheet are gummed with a suitable adhesive, so that the sheet when removed from the mandrel forms a roll capable of being slipped over the drum 22 and against theshoulder formed by the flange 33. Said drum may be slightly so that as the rolled table B is applied to he drum, it becomes snugly wedged thereon. V The sleeve 32 is formed with a longitudinal slot 37 which extends transversely. of the strip of paper from which the table B is made, said slot forming as a window in said sleeve, through whicha single row of dates upon the table B may be viewed at each setting of said 7 sleeve. Upon rotating the sleeve 32 relative to the drum 22, successive rows of dates may be exposed enabling the user to view any of the dates on the outer surface of the table B. If desired, the table B may be constructed with two months visible at one time upon the exterior of the rollso that "both the instant and the preceding month may be viewed. At the end of each month the last section of the roll is torn off along a line 36 to expose anothermonth, thereby making the table serve for an entire year.

The invention is highly advantageous in that it provides a simple and convenient calendar in association with the cap, of a fountain pen. The calendar can be incoporated in the pen without materially al tering any important portion thereof and without changing the appearance or disfiguring thepen in any manner. By arthe strip and. the dates extending an entire year may be positioned within the single filling so that the subsequent cap at a months will at all times be available as with the ordinarycalendar, giving the device the maximum degree of utility. The incorporation of the calendar with the cap does not in anyway interfere with the use of the cap in conjunction with'the pen proper, nor inf terfere with the manipulation of the pen by the writer. 7 1

Changes in the specific form of my invention, as herein disclosed,'may be made within the scope of'what is claimed without 8 invention, what If departing from the spirit of my invention.

Having described my claim as new and desire to protect by Letters Patent is 1. In combination, the cap of afountain pen having a portion thereof forming a drum-like holder, a tubular table fitting the holder, said holder having a shoulder ad-.

jacent one end thereof, a sl-eeve'revoluble upon said holder and abutting at oneend against said shoulder, said sleeve havinga window adapted to be registered with portions of said table, and a retainer secured to the other end ofsaid holder to keep sleeve in position on the holder;

2. In combination with the cap of a fountain pen having a drum-like portion at one end thereof of diameter less than said cap proper toform' a shoulder, of a table encircling said drum-like portion, a sleeve revoluble upon said portion and abutting at one end against said shoulder, said'sleeve having a window therein' for registration with a portion of said table, and a retainer fitted to said drum-like portion forming a second shoulder for engagement with the other end of said sleeve to hold the same said against longitudinal movement with respect to said drum-like portion.

3. In combination with tain pen having a tubular portion adapted to form a chamber to receive a fountain pen point, said eter less than the diameter of the cap proper, a table encircling said tubular member and'a' sleeve revoluble upon said tubua cap of foun- V tubular member being'of a diamlar member and having a window adapted to register with portions of said table.

l. In combination with a cap of a fountain pen having a drum-like portion at one end thereof of a diameter less than said cap proper to form a shoulder, a flange formed on said drum-like portion adjacent said shoulder, a sleeve revolublejupon said flange and spaced from said drum-like portion, a flange formed on the sleeve at its opposite end adapted to ride upon said drum-like portion and provide an annular space between said sleeve and drum-like portion, a table disposed Within saidspaoe, said sleeve having a Window therein registering With a portion of said table, a lug extending outwardly from said drum-like portion at one end thereof, and a retainer threaded upon said'lug and forming a stop for depriving said sleeve of longitudinal move- 10 ment.

In testimony whereof, I have signed my name to this specification.
